I bought an old classic soda dispenser and I can tell you that no matter how much you clean the root beer spout, you will always taste root beer if you switch out the drink to coke.

Same goes for coke to sprite. You can taste the coke, it’s just not as bad as the root beer.

So those old soda dispensers are supposed to be broken down and cleaned every couple of days. When I worked at a restaurant we had a service contact with Coca-Cola to do it. I worked at a TGIChillibees so it’s not like the maintenance contract was a big deal. Smaller family owned restaurants probably can’t afford it, and don’t take the time to do it.

Ya, I got sick of cleaning it that it just became a soda water dispenser. Lol
